Abu Saʿid, whoever cheerfully accepts Allah as his Lord, Islam as his religion and Muhammad as his Apostle is necessarily entitled to enter Paradise. He (Abu Saʿid) wondered at it and said: Messenger of Allah, repeat it for me. He (the Messenger of Allah) did that and said: There is another act which elevates the position of a man in Paradise to a grade one hundred (higher), and the elevation between one grade and the other is equal to the height of the heaven from the earth. He (Abu Saʿid) said: What is that act? He replied: Jihad in the way of Allah! Jihad in the way of Allah!  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ يَا أَبَا سَعِيدٍ مَنْ رَضِيَ بِاللَّهِ رَبًّا وَبِالإِسْلاَمِ دِينًا وَبِمُحَمَّدٍ نَبِيًّا وَجَبَتْ لَهُ الْجَنَّةُ فَعَجِبَ لَهَا أَبُو سَعِيدٍ فَقَالَ أَعِدْهَا عَلَىَّ يَا رَسُولَ اللَّهِ فَفَعَلَ ثُمَّ قَالَ وَأُخْرَى يُرْفَعُ بِهَا الْعَبْدُ مِائَةَ دَرَجَةٍ فِي الْجَنَّةِ مَا بَيْنَ كُلِّ دَرَجَتَيْنِ كَمَا بَيْنَ السَّمَاءِ وَالأَرْضِ قَالَ وَمَا هِيَ يَا رَسُولَ اللَّهِ قَالَ الْجِهَادُ فِي سَبِيلِ اللَّهِ الْجِهَادُ فِي سَبِيلِ اللَّهِ
